Fujitsu has launched the FTR-E3 series, a 150-A power relay that offers a minimum mechanical life of 300,000 operations and minimum electric life of 30,000 operations. The new automotive-grade relay is intended for use in EV battery-junction boxes, fast chargers, solar and industrial inverters, and the DC line of energy storage systems.
Measuring 45 mm long, 69 mm wide, and 63 mm high, the FTR-E3 series is a 1 Form X relay that features an arc extinguishing plate for arc suppression, eliminating the need for hydrogen gas and polarity in the main contact circuit, according to the company.
The FTR-E3 series is available in 12 VDC and 24 VDC models. It offers 2,500 dielectric strength, 1,000 MΩ minimum insulation resistance, and an operating temperature range of -40º to +85º C.
